Patent DE-4330367-A1 (DE)
Title: Device for motor-operated longitudinal adjustment of a seat in a motor vehicle
Inventor: KRAUTH MARCO
IPC: B60N2/02
Filed: 1993-09-08
Abstract: A device is proposed which serves for the motor-operated longitudinal adjustment of a seat in a motor vehicle. The adjustment device comprises a threaded spindle which can be driven with a reversible direction of rotation and whose two bearing elements which are arranged at a distance from one another are permanently connected to the seat and a threaded nut which is located between the bearing elements on the spindle is held fixed to the body of the vehicle. Particularly low-noise operation of the adjustment device is ensured if a spring element which acts in the direction of the spindle axis is arranged at least between the one bearing element and the threaded nut, which spring element is supported on the one hand on a shoulder of the spindle and on the other hand on a countershoulder, facing the latter, of the bearing element with pretensioning. <IMAGE>

Title: Cold-air collecting arrangement for a cooling unit
Inventor: LIM JONG-SUNG
IPC: F25D16/00
Filed: 1994-03-31
Abstract: In a cold-air collecting arrangement of a cooling unit, a phase-conversion material for storing and/or delivering cold air in accordance with the temperature change relative to a predetermined reference temperature is applied to an inner wall of a cooling-unit housing for receiving foodstuffs or is contained in this wall. The phase-conversion material collects cold air if the temperature in the cooling unit drops below the predetermined temperature and delivers cool air if the temperature in the cooling unit rises above the predetermined temperature, as a result of which the temperature in the cooling unit is kept at a suitable level.
Patent DE-4419429-A1 (DE)
Title: Optimisation of performance of supercharged gas engine
Inventor: BOZUNG HANNS-GUENTHER DR ING
IPC: F02D19/02
Filed: 1994-06-03
Abstract: The procedure for optimising the operation of a supercharged gas engine involves a main combustion chamber (2) and at least one connected preliminary chamber (7). Between 0.5% and 10% of the total gaseous fuel is highly compressed and blown into the preliminary chamber for ignition. The pressure needed for this is about two or three times higher than the pressure in the main combustion chamber. The air/fuel ratio in the preliminary chamber is less than unity, ie, it is a rich mixture. The volume of the preliminary chamber at the compression end is about 2% to 5% of the main combustion chamber volume. The preliminary chamber is made from ceramic material to improve the thermal efficiency.
Patent DE-4420063-A1 (DE)
Title: Fuel injection valve for IC engines
Inventor: MAIER FRANZ
IPC: F02M69/04
Filed: 1994-06-08
Abstract: The injection valve (8) has a pre-chamber (10) for fuel. An opening (11) can be opened and closed by a valve (13). Fuel can thus enter the chamber (14) that is separated by the injection plate (15) from the inlet valves. The plate has 2 pairs of 2 holes (17a-17b). Fuel (9a-9b) passes through the holes to the inlet valves. The closing method consists of a plate (18) that can be moved up and down. An alternative design uses a rotating plate. If the plate is in the position shown, fuel can reach all the holes. If the plate is moved down (19), the holes (17b) are covered and fuel can therefore not reach that inlet valve. The plate can be moved up and down electromagnetically.
